As an early advocate of airlifting Ethiopian Jews to Israel, he wrote an op-ed piece on the subject for New York Times[12][13][14][15] and made a documentary entitled Falasha: Exile of the Black Jews (1983).[16]

His film on the Arab-Israeli conflict, Deadly Currents (1991),[17] was runner-up for the Peace Prize at the 1991 Berlin Film Festival.[18] His film Tales from the Organ Trade (2013), co-produced and directed by his associate Ric Esther Bienstock, explored the sale of kidneys. [19]

Over the past decades, Jacobovici has engaged in what he calls "investigative archaeology." His most controversial claim is the identification of a tomb in Jerusalem as that of Jesus of Nazareth and his family. The tomb was discovered in the Talpiot neighborhood.[20] In 2012, he investigated a Second Temple-era burial cave in Armon Hanatziv by means of a robotic arm with a camera. He believes the cave may be the burial site of disciples of Jesus.[21]

His new book with Professor Barrie Wilson, The Lost Gospel: Decoding the Ancient Text That Reveals Jesus’ Marriage to Mary the Magdalene, was published in November 2014 (Pegasus in the US & HarperCollins in Canada).

Jacobovici is also the co-author of two eBooks; “Michelangelo’s Angels and Demons"[27] and “The James Revelation",[28] published by Zoomerbooks, as a companion to his television series “Biblical Conspiracies”.

In the 1983 documentary, Falasha: Exile of the Black Jews, Jacobovici tells the story of Ethiopian Jews, also called Falasha (strangers) and properly known as Beta Israel. According to the documentary, the group was conquered by neighbouring tribes in the 17th century and suffered persecution. After the movie, during the Israeli Operation Moses (Hebrew: מִבְצָע מֹשֶׁה‎, Mivtza Moshe), the Falasha were evacuated from Sudan during a famine in 1984 and airlifted to Israel.

In this 1996 documentary, Jacobovici studies the Crypto Jews of New Mexico and the tiny population of Jewish descendants in Spain and Portugal, known as nuevos Cristianos ("new Christians"). He explores the Jewish ancestry of the New Mexican Hispanic families presently living in New Mexico, and finds many of them have always been aware of their Jewish heritage.[40]

The 2002 documentary The Struma, directed by Jacobovici, tells the story of MV Struma, a small ship chartered to carry Jewish refugees from Axis-allied Romania to Mandatory Palestine in World War II. Ten people were let off the ship in Istanbul, including a woman who had just had a miscarriage,[41] and one man who was the representative of the Mobil Oil Company in Romania, and was helped by Mobil's representative in Turkey, Vehbi Koc.[citation needed] Koc asked this favour of the Istanbul Chief of Police, Sabri Caglayangil, who later became a Minister of the Interior. On February 23, 1942, with her engine inoperable and her refugee passengers aboard, Turkish authorities towed Struma from Istanbul harbor through the Bosphorus back to the Black Sea,[42] where they set her adrift without food, water, or fuel. Within hours, on the morning of February 24, she was torpedoed and sunk by the Soviet submarine Shch-213, killing at least 768 men, women, and children, and possibly as many as 791, of whom 785 were Jews.[42]

In this 2003 wide-ranging documentary, Jacobovici goes on a worldwide search for the Ten Lost Tribes of Israel (stating there are actually only nine since the remnant of the tribe of Dan was confirmed[citation needed] to be the Beta Israel of Ethiopia). Traveling from western Europe to China and India, Jacobovici finds tantalizing evidence that the "lost tribes" are, like the tribe of Dan, not really lost. The tribe of Dan is the only original tribe of Israel which is not included in the Book of Revelation's list of tribes which are sealed. No mention is made of why it is excluded.

Jacobovici suggests that the Exodus took place around 1500 BC, during the reign of pharaoh Ahmose I, and that it coincided with the Minoan eruption. In the documentary, the plagues that ravaged Egypt in the Bible are explained as having resulted from that eruption and a related limnic eruption in the Nile Delta. While much of Jacobovici's archaeological evidence for the Exodus comes from Egypt, some comes from Mycenae on mainland Greece, such as a gold ornament that somewhat resembles the Ark of the Covenant.

Jacobovici was involved in the production of a documentary shown in March 2010 on the National Geographic Channel in which he claimed that Atlantis has been found in Spain, and has said that evidence found by University of Hartford Professor Richard Freund includes the unearthed emblem of Atlantis, and that "Tarshish is Atlantis itself.”[48]
